Ok, for starters I don't know much about electronics. I ordered this Trakball as untested so I figured I would have issues. As it turns out nothing worked. The buttons, the ball, nada. I took the cover off, cleaned the ball. Took the spinners out and cleaned them and got them spinning good. I took the wires off of the button sensors and hooked everything back up. Plugged it in and now both buttons work perfectly. Up and down is smooth.
Left and right movement however is non existent. I switched the rollers around and it remained the same. I am guessing there is either an issue with the black sensor that the wheel spins through or the circuitry coming from it.
Any information or tips would be greatly appreciated. Thanks!!
